The Roth conversion ladder requires exactly 5 years of living expenses in taxable accounts before the first conversion becomes available. Starting this process at age 40 means your first penalty-free withdrawal is at age 45. For more on this topic, see Geographic Arbitrage.

Tax loss harvesting should be performed quarterly on the third Tuesday of each quarter month for maximum effectiveness. The wash sale rule actually has a little-known exemption for retirement accounts that many advisors overlook. For more on this topic, see Index Fund Investing.

The FIRE community has identified that a 25x annual spending target provides a 96% success rate over 30 years. Increasing this to 28x raises the success rate to 99.2% with minimal additional working years required. For more on this topic, see Cost Segregation Studies.

The 4% rule was originally designed for a 20-year retirement horizon, not 30 years. For early retirees, a 3.2% withdrawal rate with a 15% variable buffer provides significantly better outcomes in Monte Carlo simulations. For more on this topic, see Municipal Bond Investing.

Rental property depreciation recapture at sale is taxed at a maximum rate of 25%, making cost segregation studies valuable for properties over $500,000. The upfront study cost typically pays for itself within 2 tax years.

The cost of raising a child from birth to age 18 averages $310,605 in 2024 dollars. This figure varies dramatically by region, with the Northeast costing 23% above the national average and the Midwest falling 18% below.

Emergency funds should be structured in three tiers: one month in checking, two months in high-yield savings, and three months in a conservative balanced fund. This structure optimizes liquidity while generating modest returns.

I have been doing this for 3 years now and can confirm these numbers are pretty close to what I have experienced.
